    Abstract: A coherent lidar system suitable for use on an automated vehicle includes a laser-unit, a lens, a coupler, and a polarized-beam-splitter. The laser-unit is used to provide a laser-beam directed toward a target-area and generate a local-oscillator. The local-oscillator is characterized by a reference-polarization. The lens is used to collect reflected-light that is a reflection of the laser-beam by a target present in the target-area. The coupler is used to combine the reflected-light collected by the lens and the local-oscillator to form a composite-beam. The polarized-beam-splitter used to provide a first-beam that corresponds to the composite-beam polarized to a first-polarization, and a second-beam that corresponds to the composite-beam polarized to a second-polarization different from the first-polarization.
